I have a Neils power pipe for sale for a 05-06 M7. The pipe is a custom built works pipe that is made to run at 6-10k. The pipe is not as quiet as an slp can, more like the hps cans. The pipe is suppose to add 11hp and comes ceramic coated. I paid 1000.00 to have this pipe built this summer and now I need the money. The pipe only has 200 miles on it and if you want to see what one looks like go to www.neilspowerpipes.com I will let the pipe and silencer go for 275.00 plus shipping. This pipe was run on a carb model and I did not have to make any jetting changes but if you have an efi you will have to ask neil on what to do for jetting changes. The pipe is tight fitting but works fine.
